Hi,
Sorry if the problem has already been solved, I did not read the entire thread.

I am willing to give this miner a try but it draws far more power than claymore for a similar or little higher hashrate.

I use it with win10 with 6 RX580.
With claymore (11.9), 186Mh/s @ 830W
With Phoenix (3.5d), 187Mh/s @ 1150W!
I tried to use the same values for clocks and voltages (which are set in config.txt) or to let it blank without any effect.
What am I doing wrong?
